Super Precision Angular Contact Ball Bearings 7020 ACEGA/HCP4A

Super Precision Angular Contact Ball Bearings 7020 ACEGA/HCP4A

The 7020 ACEGA/HCP4A is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from chrome steel for durability. Its 25° contact angle and ceramic balls ensure smooth operation under radial loads up to 9518 lbf.

This open-design bearing spins efficiently at speeds up to 20,000 RPM and works in temperatures from -30°C to 110°C. The phenolic cage reduces friction, while the extra-light preload (Class A) enhances precision.

Ideal for high-speed applications like machine tool spindles or robotics, it’s interchangeable with SKF bearings. Weighing 1.12kg, it comes lubricated and meets P4A tolerance standards for reliable performance.

The bearing can be paired in back-to-back, face-to-face, or tandem arrangements for versatile use. Its universal matching feature allows easy integration into existing systems.
